I just bought this and tested it at home prior to a trip to Yellowstone, Morocco and the Sahara and believe it or not some of Florida's questionable hotel/motels. It was unbelievably soft and comfy, it kept out the air normally circulating around the body that keeps me cold in a New England winter even in my house. I am in love with this silk cocoon. It was not the least bit restrictive when sleeping, very soft to the skin and it is very small to pack with very little weight. This one is a winner! I am returning another cotton travel bag I bought at another store in favor of this one.
I spent the $$ on this due to it's compact size as I prepared for a week long bike trip where I had to get my camping gear (including tent), biking gear and 10 days worth of clothing into one 40lb bag to get on the airplane. I should've left my sleeping bag at home as I never got it out the entire week. This liner was the perfect option for summer camping. I had a fleece blanket that I took along to use as a pillow and the one night it got below 70 I got that out. Otherwise, this was all I used all week. I'm thrilled that [...]recommended this to me and I recommend it as well.
This is the second silk cocoon that I have owned. The first one was replaced by the company after it ripped down the length along a seam. Unfortunately, though I loved this liner, the second one has also ripped at the main seam. I have used this as a liner on top of a sleeping pad, with a sleeping bag over top of me and my husband. He also has a separate liner. Both of us have had issues with durability. I have washed it carefully according to directions, line dried it, and have still had durability issues. It would definitely not last on a long length bicycle tour. It did not last a week on my recent tour. I am disappointed since it is nice to be able to increase the warmth of our sleeping bag with a lightweight liner. We will be looking for something to replace this silk liner.
I was on the fence about this product, but I am very pleased to have it. I was worried it would be delicate, and my fears were misplaced. It's a durable and very light little liner. I don't think I like the drawstring very much. It's anchored to one side so you can't pull the drawstring through, but the anchored side has a little tab so you can tie the pull-side to it. I find myself pulling on the anchored side a lot. The entire drawstring feature seems pretty useless to me anyway, since I am mainly interested in protecting my bag from me, not warmth.
This is a great little liner - it's light, packs down to almost nothing, adds warmth, and keeps your sleeping bag cleaner. I've used this thing for 100+ nights over the last 4 years and it finally ripped around the edge of the "Cocoon" tag on the front. It went through the washer and dryer frequently, and it's still functional with the rip, just a little harder to use in the dark. For something as delicate as silk, I'd consider it pretty durable. I carried this almost 1000 miles on a partial thru-hike of AT and would happily carry it again.
This liner is so compact and easy to pack we take it whether staying at friend's homes, in hotels, hostels or back country camping. It prevents unnecessary body oils from getting on your sleeping bag and protects delicate skin from questionable linens. We use them with mummy bags to protect and add warmth when needed or alone if in the desert or other unforgiving hot climate. My only minor gripe is that the silk bag doesn't have much give or stretch, but for the size and security it provides, it's a minor complaint.
The liner is one of the smallest and softest and adds more warmth than some of the bigger liners. It breaths and feels great whether its hot or cold out. It packs down VERY small and makes your bag warmer so it saves space that a warmer bag would require. Its much easier to hand wash after a trip than your whole sleeping bag, especially down bags. It is very durable for how thin and delicate they seem. The price is higher than some but it is good quality and works well for many years.
I bought this for our first backpacking trip. We hiked 4 days of the Colorado Continnental Divide Trail. I bought my husband a coolmax liner, as he though the silk was too costly. Mine was half the weight, which I appreciated. I'm not sure it added 9 degrees of warmth, but it was great to have something between me and the sleeping bag. The drawstring was helpful during the cold nights. The stuff sack included is fairly easy to stuff, but I just packed my liner in my sleeping bag. We have since used our liners at places we don't trust the sheets, and for hot summer nights in the tent. The liner is easy to clean--I machine wash it and hang it to dry. It's plenty long enough and has enough room for my many sleep positions. I worry about staining it, since it's white, and I wish they made a couple's liner for snuggling.
A bag liner is essential gear after a long sweaty day on the trail. On cold nights it keeps me warmer. On cool nights I can throw my down bag over it as a blanket. On warm nights the liner might be all that I need. I could not ask for anything lighter or more compact. I am 6' 1" and I find it roomy and comfortable. After about 30 nights in it I have not noticed any durability issues. Stuffing it in the sack is always fast and hassle free.
I am not the hugest silk fan, but we were looking for liners for some recently acquired TNF bags. After a lot of persuasion by a friend we decided on the silk Cocoon and not any of the cotton or synthetic models. Using the liner completely eliminated any dead spots in the bags, and the silk is very comfortable. It does seem a bit thin, but the seams are tough and it's easy to get in to so I could see it lasting a while. On our last trip we had some very cold nights in the Mojave and both of us slept like babies. Better than some nights at home (although that might be the cat's fault). The liners are a great improvement over the nylon inside the bag since the raw bag inside was tending to turn my skin moist and greasy, apparently they protect the sleeping bag just as much! This is a great, lightweight product that does exactly what it says. The ripstop version might last a little longer (I don't know) but these seem tough and light and I couldn't be more pleased!
